What If My Patient Just Isn’t Getting Any Better? Is the patient shaking the suspension?

Did you pulse dose?

Did the pharmacist dispense generic pred?

Did the pharmacist dispense (illegally) generic FML?

Does the patient have steroid-induceduveitis?

Steroid-Induced Uveitis

First observed in steroid provocative studies in glaucoma

Incidence is higher in African-Americans (5%) than in caucasians (0.5%)

Symptoms include pain, photophobia, ciliaryflush, anterior chamber cells and/or flare

Treat by discontinuing or reducing steroid and substituting NSAID

STEROID-INDUCED OCULAR HYPERTENSION

Interesting Facts

Occurs in both healthy and glaucomatous eyes

Develops in 2-8 weeks

More prevalent with topical ketone-based steroids

Dissipates within one week after steroids are discontinued

Incidence of IOP Response

One-third of general population are “steroid responders” (≥ 3 mm Hg)

7-8% are “high” responders (≥ 10 mm Hg)

Patients Predisposed to IOP Response

Patients with POAG

Close relatives of patients with POAG

Children under 10 years of age

What To Do About It

Discontinue steroid or reduce dosing frequency

Reduce steroid concentration (↑ cost)

Change to FML or Lotemax (↑ cost)

Treat with topical ocular hypotensive agents

Avoid

Suspension vs Gel Viscosity

Shear forces from blinking

Two mechanisms cause gel to immediately thin in the eye

Interesting Facts About The Gel

No shaking required except for initial “flick” to get it into dropper tip

Essentially no blurred vision in clinical trials

pH 6.5 vs 5.5 for suspension

Specified in grams, not milliliters

5g in 10 ml bottle

STEROIDS AND CATARACT FORMATION

5/15/2013

10

Appearance of Steroid-Induced Cataract

• Posterior subcapsular

• Cannot be differentiated from early complicated cataract, radiation cataract or age-related posterior subcapsular cataract

Mechanism of Steroid-Induced Cataract Formation Formation of Schiff base intermediates

between the steroid C-20 ketone group and nucleophilic groups such as ε-amino groups of lysine residues of lens proteins

More Frequent with NonocularSteroids Oral

Inhaled

NOT intranasal

Interesting Facts About Steroid-Induced Cataracts Usual time to onset is 1 year with 10 mg/day of

prednisone (but can occur in a little as 2 months on 5 mg/day)

Incidence of oral steroid cataract is 6% to 39% Strong association between inhaled steroids and

PSC cataract No clear association between intranasal steroids and

PSC cataract Loteprednol (Lotemax) does not cause cataracts Individual susceptibility (Hispanics)

THERAPEUTIC INDICATIONS FOR

STEROIDS

Fundamental Steroid Guidelines

Choose steroid For short-term or IOP no concern

Pred Forte, Durezol, or Lotemax For long-term or IOP a concern

LE 0.5%, LE 0.2%, FML, or Vexol Pulse-dose Monitor IOP in first 2-6 weeks NO REFILLS! Use shortest effective course of therapy Avoid in presence of epithelial HSV, mycobacterial,

and fungal infection

5/15/2013

Infiltrative Keratitis/CLARE

CLARE

Initially thought to be primarily due to hypoxia

An inflammatory response to toxins produced by less virulent strains of gram negative bacteria

Recurrent episodes common

CLARE is NOT a marker for microbial keratitis

Sweeney, et al. Eye Contact Lens 2007

Differential Diagnosis of Corneal Ulcers vs. Sterile Infiltrates

Ulcer (MK) Rare

Usually painful

Tend to be central

1 to 1 staining defect to lesion ratio

Cells in anterior chamber

Generalized conjunctivalinjection

Usually solitary lesion

Possible tear lake debris

Eyelid swollen

Infiltrate

Common

Mild pain

Tend to be peripheral

Staining defect size relatively small

No cells in anterior chamber

Sector skewed injection pattern

Can be multiple lesions

Clear tear lake

Eyelid not swollen

Infiltrate

Common

Mild pain

Tend to be peripheral

Staining defect size relatively small

12

Management of CLARE

Topical steroid alone If cornea is clear/no epithelial

compromise Combination antibiotic/steroid

Pulse-dose q2h for 1-2 days, then q.i.d. for 4-5 days

Address CL hygiene and wearing time: Daily wear only!Otherwise, CLARE is likely to recur

Preferred Antibiotic-Steroid Combos

Steroids in Microbial Keratitis

Steroids for Corneal Ulcers Trial (SCUT)

Srinivasan M, et al. Arch Ophthalmol 2012;130(2):143-150.

SCUT Conclusions

“Conclusions: We found no overall difference in 3-month BSCVA and no safety concerns with adjunctive corticosteroid therapy for bacterial corneal ulcers.”

“Application to Clinical Practice: Adjunctive topical corticosteroid use does not improve 3-month vision in patients with bacterial corneal ulcers.”*

*Exceptions: Patients with “finger counting” VA or worse at baseline, and patients with completely central ulcers.

Management of GPC

Discontinue contact lens wear if possible

If not, use daily disposables

Educate patient on CL hygiene, wearing schedule, etc.

Lotemax for Treatment of Dry Eye Inflammation Lotemax was compared with placebo for

treatment of the inflammatory component of dry eye

Randomized, double-masked, placebo-controlled, multicenter comparison

Patients with dry eye (n=66) 32 patients treated with Lotemax 34 patients treated with placebo

Subjects received either Lotemax or placebo QID in both eyes for 4 weeks

Pflugfelder SC, Maskin SL, Anderson B, et al. Am J Ophthalmol 2004; 138: 444-57.

Lotemax for Treatment of Dry Eye Inflammation When used as monotherapy, Lotemax resulted in

greater improvement in objective signs and symptoms of dry eye than placebo at both 2 and 4 weeks

Lotemax demonstrated no clinically significant IOP elevation following 1 month of therapy

Pretreatment with Lotemax prior to cyclosporine treatment showed: 75% lower stinging rate 68% lower rate of discontinuation with

cyclosporine therapySheppard JD, et al. Topical loteprednol pretreatment reduces cyclosporine

stinging in chronic dry eye disease. J Ocul Pharmacol Ther. 2011;27:23-7

Recommended Treatment Approach for Dry Eye Inflammation

Artificial Tears

Lotemax® BID(loteprednol etabonate ophthalmicsuspension 0.5%)

Why Do Antihistamines Cause Dry Eye?

5/15/2013

16

Parasympathetic (Cholinergic) Innervation of Lacrimal Gland

Antihistamines

• H1 blockers reduce both aqueous and mucinproduction

• As little as 4 mg daily of chlorpheniramine maleate can produce positive Schirmer test

• Four days of once-daily loratadine (Claritin) can induce dry eye and corneal staining

• Can aggravate underlying condition of dry eye

Minimal or no signs

Palliative measures; Possibly antihistamine/ mast cell stabilizer

Level 2 Primary reason for visit is itching/other symptoms; Lifestyle is affected

Minimal or no signs

Topical steroid q.i.d. for 2 weeks, then b.i.d. for 1-2 months, then switch to anantihistamine/mast cell stabilizer if symptoms persist

Level 3 Primary reason for visit is itching/other symptoms; Lifestyle is greatly affected

Red eyes; conjunctival congestion or chemosis

Steroids in SAC Management No longer considered a last resort Limit therapy to ester-based steroids (loteprednol) Use when there are significant signs or more severe

symptoms In severe cases, dosing can be increased to q2 h for the

first 2-3 days (while awake) Schedule follow-up at 3-4 weeks to check IOP and

therapeutic response No adverse effects reported with up to 4,000 doses of

Alrex over 36 months* IOP spikes can rarely occur

OTC ketotifen is comparable to olopatadine 0.1% (Patanol) in reducing itching associated with SAC, although possibly somewhat less comfortable
